d'OHN N. NELSON, OF ROCHESTER, NEW YORK, ASSIGNOR TO UNIVERSAL OPTICAL COR- PORATION, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND OPHTHALMIC MOUNTING Application filed April 17,

My present invention relates to improvements in opthalmic mounting, more particularly to the nose guard members thereof and to the method of forming the same.

One object of this invention is to provide a nose guard having a body portion formed of non-metallic material and having a core of bendable metal inserted or imbedded into the body portion and also having a bendable metallic arm with one end portion inserted into this non-metallic body.

A further object of the invention is to form the body portion of the guard of a single piece of non-metallic material such for instance, as celluloid or thelike and to insert a blade or other core of metal, preferably by softening the body and then forcing this blade thereinto, and also forcing one end of the bendable metallic arm into this body to securely anchor this end therein.

lVith these and other objects and advantageous features in view, the invention consists of novel arrangements of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawing, and more particularly set forth in the appended claims.

In the drawing:

Fig. l is an elevation partly broken away, showing the novel nose guards secured to the bridge piece of the mounting;

Fig. 2 shows a block or single piece of nonmetallic material with the blade in position to be forced endwise thereinto;

Fig. 3 indicates the blade in dotted lines as having been forced and imbedded into the body portion and showing the entering slot at the end of this body;

Fig. 4 is a perspective view of the bendable metallic attaching arm for the guard, showing the locking notches in one end thereof;

Fig. 5 is a View partly in section showing the metallic blade as inserted into the nonnon-metallic body;

Fig. 6 is an edge View of the non-metallic body indicating the core blade as inserted therein and the bendable arm as extending 1930. Serial 110,444,982.

It has been found desirable in the construction of ophthalmic mountings to provide the body portion of the nose guard of non-metallic material, thus eliminating any tendency to tarnish or corrode and adding to the comfort to the user, and to the decorative effect, and also to reduce tothe minimumthe cost of manufacture.

Owing to the fact that it is desirable that the body portion of the nose guard be bendable to conform to the contour of that portion of the face with which it comes in contact, it is necessary that bendable material shall be inserted into the celluloid or non-metallic body portion thereof; and to accomplish this in a simple and effective way, I provide a core;

which may be made in any suitable form such as a blade, a strip, a wire or metal in other suitable forms, and I insert this metallic core into this non-metallic body, preferably by softening this body either by application of heat or suitable chemicals to such an extent that this core may be forced and imbedded into the body and the opening through which it enters to be subsequently sealed thereby completely concealing the metal in the nonmetallic body. I also provide one end of a bendable attaching arm for the body with I notches or the like, and also force this prepared end of the arm into the edgeof the non-metallic body. Then I subsequently complete the shaping of this non-metallicbody preferably by milling or otherwise cutting away the stock, to nicely round the edges and obtain a pleasing contour of this body member; and the following is a detailed description of the present embodiment of my invention and showing the preferred con-' struction by which these advantageous results may be accomplished. V y j With reference to the drawing, 10 desig nates the blank of material such as celluloid, zylonite or other similar material, which may be roughed out into a suitable form; I then soften this blank either by the application' of heat or the application of suitable chemicals thereto, and I then force a stiffening metallic core into this body 10, which core maybe ing may be sealed and closed to entirely conceal the blade imbedded in the body. 1

then provide a bendable arm member 14 preferably of metal with one end notched as at 15 and I force this notched end into the edge of the non-metallic body, the softened material being caused to flow into these notches 15 to secure, lock or anchor this end of the arm firmly therein, It is now only necessary to trim and round the edges of the body 10 which is preferably done by a 'milling operation to remove the surplus stock and form the body with the desired contour With nicely rounded edges.

By this construction, it will be seen that by the use of this metal core in the non-metallic body, I am enabled to bend the body into any desired positionand the metal being of a bendable and ductile nature, will cause the body to remain inthe bent shape.

Having thus described one illustrative em-, bodiment ofmy invention and the best mode known to me for carrying out my method, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for the purpose of limitation, the scope of the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A method of forming a non-metallic nose guard body portion with a bendable metallic blade, which consists in softening the body portion and forcing the bendable metallic blade into the body, and inserting the end of a'separate attaching arm into the nonmetallic body from a direction different from the insertion of said blade while the body is softened to permanently connect the arm thereto.

2. A method of forming a non-metalli nose guard body portion with a metallic core, which consists in softening the body portion, forcing a blade having a piercing entering edge thereinto, sealing the entering opening, and inserting the end of an attaching arm into the non-metallic body while softened to permanently connect the arm thereto.

3. In an ophthalmic mounting, a nose guard having a body portion formed of a single solid non-metallic bendable piece, a bendable metallic blade imbedded within the walls of said body, and a separate attaching arm having one end portion rigidly anchored in said body.

4. In an ophthalmic mounting, a nose guard having a body portion formed of a solid piece of non-metallic material, a bendable metallic blade imbedded and sealed within the walls of said body, and a separate bendable metallic arm having one end por tion provided with locking means imbedded and anchored in said body.

5. In an ophthalmic mounting, a nose guard having a body portion formed of a solid piece of non-metallic material, a bend.- able metallic blade having a thin surrounding piercing edge and imbedded and sealed'within the walls of said body, and a separate bendable metallic arm having one end portion provided with locking means imbedded and anchored in said body.

6. In an ophthalmic mounting, in combination, a bendable metallic blade of a width greater than its thickness, a separate bendable arm, and a bendable non-metallic covering body surrounding .and looking together said metallic blade and one end of said bendable arm, said metal parts being closely adjacent one to the other.

7. In an ophthalmic mounting, a nose guard having a body portion formed of a single solid non-metallic bendable piece, a bendable metallic blade imbedded within the Walls of said body, and a separate metal attaching arm having one end portion rigidly anchored in said body.

In testimony whereof I aflix my signature.

JOHN N. NELSON.
